Answer:
6) 225.8 g
7) 1.01 g
8) 21.624 g
Explanation:
6) Molar Mass of Lithium Bromine: 86.845
86.845 * 2.6 = 225.8 g
7) Molar Mass of Neon: 20.180
20.180 * 0.05 = 1.01 g
8) Molar Mass of Water Vapor: 18.02
18.02 * 1.2 = 21.624 g
Hydrogen
Hydrogen is identified by the glowing splint described in the question.
Answer: B or C
Explanation: The question does not include the variable or steps Brian is using so either one could be correct. It has to be the one that he is controlling though. This is because a control group is used to rule out any alternate explanations. Therefore the answer should be the one that he is trying to test out.
The nuclear equation for
formation of iron-54 through fusion would be Fe + heat ----> Fe_54 + +
neutrons. I am hoping that this answer has satisfied your query
about and it will be able to help you, and if you’d like, feel free to ask
another question.
N2 + 3H2 produces 2NH3 If that is the correct chemical equation.
Reactants
N = 2
H =6
Products
N =2
H= 6
The answer is just one.
